Authorities in the disappearance of baby Lisa case are now looking into questioning the girl's older brothers, ages 6 and 8, to try to get to the bottom of what exactly happened the night she vanished.

After the Irwin family failed to cooperate properly with police, Deborah Bradley and Jeremy Irwin have given the okay to let the boys be interviewed.

The attorney for Deborah and Jeremy has said that they are willing to cooperate with authorities:

The search for missing baby Lisa Irwin is still underway as police begin to search in a landfill.

Before we get into the current part of the Lisa Irwin saga, let's recap for you…

On Tuesday, October 4, the father returns home from work around 3:30am to discover the 10-month-old baby missing from her crib.

An amber alert was issued.

Around 7pm, the amber alert is cancelled. At this point, Lisa is considered a missing/endangered juvenile. Police and dogs continue to search.

Since then, the police have remained persistent, but there seems to be some misunderstanding between the police and the baby's parents — Jeremy Irwin and Deborah Bradley. After days of consistent cooperation, the police recently announced that the parents quit cooperation.
